A Call For Equity In Genomics Research
12 november 2020 · 15 min
In the future, genomic research could lead to new treatments for human disease. It turns the data in our DNA into a global commodity. But historically, minoritized communities have been left out of this research. Keolu Fox is a genome scientist trying to change that and advocate for a more equitable approach when Indigenous and other underrepresented communities do participate. Lees meer

What's It Like To Be A COVID-19 'Long Hauler'
9 november 2020 · 15 min

Why These Tiny Particles Are A Big Deal

Quantum Mechanics For Beginners
19 oktober 2020 · 11 min
Monika Schleier-Smith, associate professor of physics at Stanford University, studies quantum mechanics, the theory that explains the nature of the itty bitty parts of our universe: atoms, photons, and individual particles. It's the science responsible for innovations in computers, telecommunications, and medicine. Schleier-Smith was recently awarded a 2020 MacArthur Fellowship for her work in the field. It's research that often starts in a lab and as Schleier-Smith describes, requires both troubleshooting and optimism. Lees meer

The CDC Doesn't Know Enough About Coronavirus In Tribal Nations

A recent CDC report estimates Native Americans and Alaskan Natives are 3.5 times more likely to get COVID-19 than white people, and those under 18 are more likely to test positive. Lees meer
This report is the first time the federal government has released hard numbers on the coronavirus in tribal nations, but it is most notable for what it does not say about how the virus is affecting Native Americans and Alaskan Natives. And some scientists believe that the CDC's current numbers are an underestimate.
Jourdan Bennett-Begaye, reporter and deputy managing editor of Indian Country Today, explains why the CDC data is so limited in scope — and her efforts to bring more data transparency to the table.

Managing Wildfire Through Cultural Burning
9 september 2020 · 13 min
Fire has always been part of California's landscape. But long before the vast blazes of recent years, Native American tribes held controlled burns that cleared out underbrush, encouraged new plant growth, and helped manage wildfires. It's a tradition that disappeared with the arrival of Western settlers. NPR climate correspondent Lauren Sommer explains how tribal leaders are trying to restore the practice by partnering up with state officials who are starting to see cultural burns as a way to help bring extreme wildfires under control.
